ERROR: Conversion failed!

(i don't have a verbose log, but the issue is obvious)

Description

When the disk is full (0 byte free), i get this error.

Please show helpful error message like when downloading.

ERROR: unable to download video data: [Errno 28] No space left on device

[davidak]

OK, now i have tested it with the latest version and have steps to reproduce!

Steps to reproduce:

1. see how much free disk space you have

[davidak@X230:~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        386M     0  386M   0% /dev
tmpfs           3,8G  792M  3,0G  21% /dev/shm
tmpfs           1,9G  5,8M  1,9G   1% /run
tmpfs           3,8G  408K  3,8G   1% /run/wrappers
/dev/dm-2       220G  197G   12G  95% /
tmpfs           3,8G     0  3,8G   0% /sys/fs/cgroup
/dev/sda1       477M   94M  354M  21% /boot
tmpfs           3,8G   32M  3,8G   1% /tmp
tmpfs           771M  108K  771M   1% /run/user/1000

I have 12 GB on /.

2. fill the free space with zeroes

[davidak@X230:~]$ dd if=/dev/zero of=file.txt count=1024 bs=12024000
1024+0 records in
1024+0 records out
12312576000 bytes (12 GB, 11 GiB) copied, 75,8542 s, 162 MB/s

3. check the disk is fill

[davidak@X230:~]$ df -h
Filesystem      Size  Used Avail Use% Mounted on
devtmpfs        386M     0  386M   0% /dev
tmpfs           3,8G  802M  3,0G  21% /dev/shm
tmpfs           1,9G  5,8M  1,9G   1% /run
tmpfs           3,8G  408K  3,8G   1% /run/wrappers
/dev/dm-2       220G  209G     0 100% /
tmpfs           3,8G     0  3,8G   0% /sys/fs/cgroup
/dev/sda1       477M   94M  354M  21% /boot
tmpfs           3,8G   32M  3,8G   1% /tmp
tmpfs           771M   96K  771M   1% /run/user/1000

avail should be 0

3. execute command

the download fails first before conversion even starts...

the behavior here is that the download of one fragment fails because disk is full (clear error message) and it is skipped, next fragment is downloaded and fails also... it might be better to directly fail when disk is full
